Title: Carrier detection circuit
Inventor: ADACHI HIROAKI
IPC: H04B1/16
Filed: 1985-06-21
Abstract: PURPOSE:To widen a range where an input point voltage is unchanged due to the quantity of the C/N when no carrier exists by providing a lower limit limiter circuit not lowering a voltage at a low pass filter output voltage input terminal of a carrier discrimination circuit to a prescribed value or below. CONSTITUTION:The lower limit limiter circuit comprised of an IC3 and an X3 is provided to the output section of a low pass filter comprised of R1 and C1 and its limiter potential is changed by an RV1. In selecting the lower limit potential to a voltage VL slightly lower than a reference voltage Vref1 of an operational amplifier IC1, the characteristic of the low pass filter output voltage versus C/N is as shown in figure. That is, the limiter voltage (VL) is constant by the limiter circuit up to the region of infinite C/N except the region of C/N with 5dB or below. Then the lower limit of the delay time of the detection output at the carrier input of a carrier detection circuit is nearly constant and the C/N is decided uniformly from nearly 5dB to infinite value by using a time constant comprised of R6 and C3.

Title: Sheet feed device
Inventor: SUGA YOICHI
IPC: B65H1/26
Filed: 1989-05-31
Abstract: PURPOSE:To prevent last double feeding when thick sheets are supplied and fed by providing high friction sheets at the portions situated below separating claws when side guide members for guiding both side ends of the thick sheets are mounted to the sheet feed device. CONSTITUTION:When common sheets 4a are loaded on loading members 3 and fed, the common sheets 4a are separated and fed in such manner as to get over separating claws 6. When thick sheets 4b are fed, thick sheet side guide members 8 are mounted to the loading members 3. Thus, the thick sheets 4b are separated and fed through the slits of the separating claws 6 with their both sides being guided. Further, in this case, since high friction sheets 9 are positioned below the separating claws 6, the last sheet is brought into pressure- contact with the high friction sheets 9 by the separating claws 6 regardless of the state of a sheet feeding means, and thereby the generation of double last feeding can be prevented.

Title: White balance correcting circuit
Inventor: SAITO MASAHISA
IPC: H04N9/04
Filed: 1992-04-28
Abstract: PURPOSE:To reduce the white balance correction error at the time of picking up the image of an object having a high saturation by setting a required minimum white part detection area. CONSTITUTION:Gain control circuits 1 and 2 subject R and B signals to gain control. A white position detecting circuit 30 detects a signal position corresponding to an object having a low saturation by color difference signals R-Y and B-Y and a luminance signal to output a detection signal. Gate circuits 4 and 5 extract signal parts corresponding to the object having a low saturation from color difference signals based on this detection signal, and integrators 6 and 7 integrate these signals. Comparators 8 and 9 to D/A converters 12 and 13 supply control signals to gain control circuits 1 and 2. When the image of the object having a high saturation overall is picked up, that is, when the output of the white position detecting circuit 30 is in the high level, a gate area switching circuit 24 substitutes this output with a signal equivalent to the detection signal for pickup of the image of the object having a low saturation overall, namely, a signal in the low level and outputs this signal.

Title: Inspection method for food with x-ray
Inventor: ISHIKAWA SEIJI
IPC: G01N23/04
Filed: 1987-05-30
Abstract: PURPOSE:To easily detect foreign matter in food in an undefined shape by projecting an X-ray while food is dipped in water. CONSTITUTION:The food 4 to be inspected is put in a container 3, which is filled with water and radiated with the X ray from an X-ray generation bulb 2. The X-ray transmitted through the food dipped in water is absorbed by a fluorescent plate 6 and converted into visible light. The visible light matching with the quantity of the transmitted X-ray converted by the fluorescent plate 6 is reflected by a reflecting mirror 7 and its X-ray tomographic image can be observed through an observation window 9. Animal and vegetable foods normally contain much water, and their X-ray absorptivity is close to that of the water. A difference in X-ray absorption quantity due to the ruggedness of food is compensated by the water and the X-ray tomographic image of the food to be inspected is uniformed in density. Consequently, if the food to be inspected contains foreign matter having X-ray absorptivity different from that of the food, the part appears in the image as a density difference of the X-ray tomographic image corresponding to the difference in X-ray absorptivity or is converted into a signal, so the foreign matter is easily detected.

Filed: 1984-07-02
Abstract: PURPOSE:To reduce a non-linear error, and to adjust a spot interval with high accuracy by synthesizing optically plural optical beams whose wavelength is different from each other by using a dichroic mirror, and adjusting the beam spot interval by changing an angle of the mirror. CONSTITUTION:Optical beams B1, B2 whose wavelength is different from each other from laser light sources 11, 12 are made incident on a dichroic mirror 9, and synthesized optically to one beam by making the optical axis approach optionally by the mirror 9. Subsequently, this synthesized light is reflected by a polygon mirror 6 and projected to a photosensitive drum 8, but in that case, a beam spot interval is adjusted by driving an actuator 11 and changing an angle of the mirror 9. Accordingly, since the dichroic mirror 9 is used, the optical axis can be made to approach optionally, and a non-linear error can be reduced. Also, since the interval can be adjusted by only changing the angle of the mirror 9, the spot interval can be adjusted with a high accuracy.
